Description

Die Erfindung bezieht sich auf eine Heizeinrichtung für Vorrichtungen zum Verkleben f1ächenförmiger Textilstücke mit einer Heizstation, die mehrere Heizbereiche aufweist, deren elektrische Heizkörper einzeln ein- oder ausschaltbar sind, so daß bestimmte Kombinationen von Heizkörpern wirksam bzw. unwirksam sind.The invention relates to a heating device for devices for gluing flat pieces of textile with a heating station, which has several heating areas, their electric heating elements individually can be switched on or off so that certain combinations of radiators are effective or ineffective.

Eine derartige Heizeinrichtung ist aus der" DE-PS 26 48 724 bekannt. Dort sind die einzelnen Heizkörper einzeln ansteuerbar und zur Erzielung einer vorgege-Such a heating device is from "DE-PS 26 48 724 known. There the individual radiators can be controlled individually and to achieve a pre-set

benen Aufheizkurve in einer bestimmten Kombination einschaltbar. Der Grundgedanke dieser bekannten Heizeinrichtung liegt darin, daß sich die wirksame Länge der Heizzone durch Zu- und Abschalten von vorgegebenen Heizbereichen variieren läßt und daß durch vorgegebene Schaltkombinationen von Heizbereichen der Aufheizvorgang der zu verklebenden Textilstücke über die Zeit ihres Durchlaufs durch die Heizzone in relativ weiten Grenzen verändert werden kann. Die einzelnen Heizkörper können hierbei allerdings nur entweder voll eingeschaltet oder voll abgeschaltet sein.The heating curve can be switched on in a specific combination. The basic idea of this known heating device lies in the fact that the effective length of the heating zone is determined by switching on and off predetermined Heating areas can be varied and that the heating process is controlled by predetermined switching combinations of heating areas of the textile pieces to be bonded over the time of their passage through the heating zone in relatively wide areas Limits can be changed. The individual radiators can only either be full switched on or completely switched off.

Hiermit läßt sich jedoch noch nicht immer eine optimale Aufheizung der zu verklebenden Textilstücke erreichen.In this way, however, it is not always possible to achieve optimal heating of the textile pieces to be bonded.

Insbesondere läßt sich die Temperatur nicht feinfühlig 15In particular, the temperature cannot be sensitive 15th

Aufgabe der Erfindung ist es, die Heizeinrichtung der eingangs genannten Art dahingehend zu verbessern, daß eine den jeweils zu verklebenden Textiistücken optimal angepaßte Aufheizung erzielt werden kann.The object of the invention is the heating device of the aforementioned type to the effect that one of the pieces of text to be glued optimally adapted heating can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Heizkörper einzeln oder gruppenweise zusätzlich auf unterschiedliche Leistungsaufnahme umsteuerbar sind.According to the invention, this object is achieved by that the radiators can be switched individually or in groups to different power consumption are.

Hierdurch wird eine feinfühligere Einstellung der Temperatur einzelner Heizkörper erreicht, so daß zeitlich und/oder räumlich beliebige Temperaturverteilungen erreicht werden können, ohne daß durch Einschwingvorp. gänge verursachte Temperaturabweichungen hingenommen werden müssen. Insbesondere kann einerseits eine sehr schnelle Aufheizung erfolgen und andererseits eine sehr exakte Nachregelung kleiner Temperaturabweichungen von der Sol I-Temperatur durchgeführt werden. Zusätzlich ist von Vorteil, daß während der Nachregelungsphase, d.h. wenn nur kleine Temperaturabweichungen gegenüber der Sol I-Temperatur vorliegen, keine großen Ströme geschaltet werden müssen und keine stoßartige Belastung des Energieversorgungsnetzes auftritt.This enables a more sensitive setting of the Temperature of individual radiators reached, so that any temperature distributions in terms of time and / or space can be achieved without the need for transient prep. temperature deviations caused by corridors must be accepted. In particular, on the one hand, a very rapid heating and, on the other hand, a very precise readjustment of small temperature deviations from the Sol I temperature. In addition, it is advantageous that during the readjustment phase, i.e. if there are only small temperature deviations compared to the Sol I temperature, no large ones Currents have to be switched and there is no sudden load on the power supply network.

Nach einer Variante der Erfindung weisen die einzelnenAccording to a variant of the invention, the individual

Heizkörper individuell zugeordnete Leistungsstelleinrichtungen auf. Hierbei kommen Thyristoren und Trial-Einrichtungen in Frage, mit denen die den einzelnen - Heizkörpern zugeführte elektrische Leistung verändert werden kann.Radiator individually assigned power control devices on. Here thyristors and trial devices come into question, with which the individual - The electrical power supplied to radiators has changed can be.

Nach einer anderen Variante sind die einzelnen Heizkörper gruppenweise zwischen Serien- und Parallelschaltung umschaltbar. Werden beispielsweise jeweils zwei Heizkörper zu einer Gruppe zusammengefaßt, soAccording to another variant, the individual radiators are grouped between series and parallel connection switchable. For example, each two radiators combined into a group, like this

können diese Heizkörper als Gruppe in Serienschaltung oder in Parallelschaltung betrieben werden, wobei die aufgenommene Leistung bei Serienschaltung ein Viertel derjenigen bei Parallelschaltung ist.these radiators can be connected in series as a group or operated in parallel, whereby the power consumed in series connection is a quarter of that in parallel connection.

Nach einer vorteilhaften Ausgestaltung dieses Gedankens weisen die einzelnen Heizkörper jeweils zwei oder mehrere Heizdrä'hte auf, die heizkörperweise zwischen Serien- und Parallelschaltung umschaltbar sind. Hierdurch kann jeder einzelne Heizkörper in sehr einfacher Weise unabhängig von anderen Heizkörpern individuell in seiner Energieaufnahme und damit seiner Temperatur eingestellt werden.According to an advantageous embodiment of this idea the individual radiators each have two or more Heizdrä'hte, the radiator between Series and parallel connection can be switched. Through this can make every single radiator in a very simple way Way independently of other radiators individually in its energy consumption and thus its temperature can be set.

_ Nach einer weiteren vorteilhaften Ausgestaltung der_ According to a further advantageous embodiment of the

Erfindung sind die einzelnen Heizkörper bzw. die einzelnen Heizdrähte eines oder mehrerer Heizkörper gruppenweise an eine Drehstromenergieversorgung angeschlossen. Hierbei ist dann in besonders vorteilhafter Weise eine Regelung bzw. Einstellung der Energieaufnahme dadurch möglich, daß die Heizkörpergruppen zwischen Stern- und Dreieckschaltung umschaltbar sind. Diese Maßnahme kann sowohl für sich alleine als auch in Kombination mit der Umschaltmöglichkeit zwischen Parallel- und Reihenschaltung durchgeführt werden. In letzterem Fall können mehrere Heizkörper oder Heizdrähte eines Heizkörpers zu einer ersten Gruppe zusammengefaßt sein, die wahlweise zwischen Parallel- und Reihenschaltung umschaltbar sind. Je eine solche __ Gruppe kann dann zusätzlich einen Zweig darstellen, der zusammen mit weiteren solchen Zweigen wahlweise als Stern- oder Dreieckschaltung mit der Drehstrom-Energieversorgung verbindbar ist. Mit dieser Maßnahme kann eine noch feinstufigere Regelung durchgeführtInvention are the individual radiators or the individual heating wires of one or more radiators in groups connected to a three-phase power supply. This is then particularly advantageous a regulation or setting of the energy consumption possible in that the radiator groups between Star and delta connections are switchable. These Measure can both on its own and in combination with the option to switch between Parallel and series connection can be carried out. In the latter case, several radiators or heating wires of a radiator can be combined to form a first group which can be switched between parallel and series connection. One such __ Group can then also represent a branch, which, together with other such branches, optionally as a star or delta connection with the three-phase power supply is connectable. With this measure, an even more finely graded control can be carried out

Zur Steuerung und Regelung der gesamten Heizeinrichtung ist ein Steuer- und Regelkreis vorgesehen, der zusammen mit mindestens einem Temperaturfühler die einzelnen Heizkörper auf die jeweils optimale Leistungsaufnahme umsteuert, wodurch ein vorgegebener zeitlicher und/ örtlicher Temperaturverlauf der Heizbereiche realisierbar ist.For controlling and regulating the entire heating system a control and regulating circuit is provided which, together with at least one temperature sensor, controls the individual Radiator to the optimal power consumption in each case reversed, whereby a predetermined temporal and / local temperature profile of the heating areas can be realized is.

Die gemeinsamen Verbindungspunkte zweier elektrisch benachbarter Heizdrähte sind jeweils mitAnother variant of the heater is related shown with FIG. 11. There are several heating wires Rl-Rl2 in series firmly with one another wired. The common connection points of two electrically adjacent heating wires are each with

einem Schaltkontakt eines zugeordneten 3-poligen Schalters S1-S12 verbunden. Jeweils ein Pol (in Fig. 11 der linke) jedes der Schalter S1-S12 ist mit einem Pol der Energieversorgung N verbunden. Ein Pol jedes elektrischen Schalters ist "neutral", d.h. elektrischa switching contact of an assigned 3-pole switch S1-S12 connected. One pole (the left one in FIG. 11) of each of the switches S1-S12 is connected to one Pole of the power supply N connected. One pole each electrical switch is "neutral", i.e. electrical

potentialfrei. Der dritte Pol jedes der Schalter Sl-S12 ist mit dem anderen Pol der Energieversorgung N verbunden.potential free. The third pole of each of the switches S1-S12 is connected to the other pole of the power supply N.

In der Tabelle der Fig. 11 sind verscheidene möglicheIn the table of FIG. 11 there are several possible

Schaltkombinationen dargestellt. Ein "+" bedeutet,Switching combinations shown. A "+" means

daß der zugehörige Schaltkontakt in der linken Stellung ist, während ein "-" bedeutet, daß der Schaltkontakt in der rechten Stellung in Fig. 11 ist. Eine "0" bezeichnet die neutrale Stellung.that the associated switch contact is in the left position is, while a "-" means that the switch contact is in the right position in FIG. A "0" indicates the neutral position.

In dem dargestellten AusfUhrungsbeispiel ist der "Eingang" des ersten Heizdrahtes Rl ohne Zwischenschaltung eines Schalters direkt mit einem Pol der Energieversorgung verbunden, während der "Ausgang" des letzten Heizdrahtes R12 über einen Schalter S12 analog zu den übrigen Schaltern mit der Energieversorgung verbunden ist. Natürlich könnte auch der erste Heizdraht Rl über einen entsprechenden Schalter mit der Energieversorgung verbunden sein. Das Grundprinzip der Schalte terstel1ungen ist wie folgt:In the exemplary embodiment shown, the "input" of the first heating wire Rl without the interposition of a switch directly to a pole of the energy supply connected, while the "output" of the last heating wire R12 via a switch S12 analogous to the other switches are connected to the power supply. Of course, the first heating wire could also be used Rl be connected to the power supply via a corresponding switch. The basic principle of the switch setup is as follows:

Sind die Schalter an beiden Anschlüssen eines Heizelementes in gleicher Stellung, so liegt an beiden Anschlüssen des Heizelementes das gleiche Potential, so daß dieses Heizelement unwirksam ist. Liegen die entsprechenden Schalter am "Eingang" und "Ausgang" eines Heizdrahtes in zwei entgegengesetzten Lagen (d.h. nicht in der neutralen Stellung), so liegt die volle Netzspannung an dem betreffenden Heizdraht (Parallelschaltung). Liegt ein Schalter in der neutralen Stellung, so sind die beiden elektrisch vor und hinter ihm liegenden Heizdrähte in Reihenschaltung geschaltet. Sind beispielsweise die Schalter Sl - SIl der Fig. 1 in neutraler Stellung und ist der Schalter S12 in der rechten Schaltstellung, so liegen alle Heizdrähte g0 R1-R12 in Reihe hintereinander. Weitere Schaltkombinationen sind aus der Tabelle der Fig. 1 entnehmbar.If the switches at both connections of a heating element are in the same position, the same potential is applied to both connections of the heating element, so that this heating element is ineffective. If the corresponding switches at the "input" and "output" of a heating wire are in two opposite positions (ie not in the neutral position), then the full mains voltage is applied to the heating wire concerned (parallel connection). If a switch is in the neutral position, the two electrical heating wires in front of and behind it are connected in series. If, for example, the switches S1-SIl of FIG. 1 are in the neutral position and the switch S12 is in the right switch position, then all the heating wires g 0 R1-R12 are in series one behind the other. Further switching combinations can be found in the table in FIG. 1.

Die Schalter S1-S12 werden über den Steuer- und Regelkreis 51 betätigt. Die Betätigung kann hierbei elektrisch, beispielsweise über Magnetspulen erfolgen oder auch mechanisch über ein Walzensteuerwerk. Es ist ersichtlich, daß mit der verhältnismäßig einfachenThe switches S1-S12 are actuated via the control and regulating circuit 51. The actuation can be electrical, take place, for example, via magnetic coils or mechanically via a roller control unit. It can be seen that with the relatively simple
